Air and water temperatures remained consistent and did not show any outstanding difference from one year to the next.

Conductivity levels also remained consistent with the exception of site 3A which showed a spike with an average conductivity reading of 240 µS/cm. In 2012 sites 3A and 4A were the only two sites to have averages of 150 µS/cm or higher, while no sites in 2011 met this standard. The increase at site 3A is more likely caused by pollution entering the water than an improvement in stream health since readings at site 2B were 106 µS/cm and 3B were 140 µS/cm.

For both 2011 and 2012 all sites were within the range suggested by the EPA of 6 to 8 as healthy pH levels. The only unique difference was the increase of pH from 6.3 to 7.5 at site 2A. Since the increase was more than a factor difference, it suggests a change in water quality at this particular site.

Dissolved oxygen levels did not show much variation from one year to the next with the exception of sites 1A and 1B. These two sites were the only sites in 2012 not to meet the 4mg/L standard set by the EPA. This was most likely cause by the complete lack flow two out of the three test days.
